A case study of the activin gene in avian species was carried out using bioinformatics. As a sedentary bird, guinea fowl is more susceptible to local selection processes and needs a proper genetic study for conservation. The present study provides the basis for the use of activin or its target genes for the improvement of impaired wound healing, and activin antagonists for the prevention and treatment of fibrosis and the end of malignant tumors that over-express activin. The information provided will serve as a basic tool for broader genetic diversity studies to identify valuable poultry genetic resources and major genes for the development of breeding programs. This study was done by retrieving hundred (100) nucleotides and amino acid sequences of the activin gene belonging to guinea fowl and other avians from the GeneBank, aligning the sequences using BlastP determined the percent identity and phylogenetic relationship of the activin gene of guinea fowl and other avians. The shortest activin nucleotide sequence (467 bp) was observed in chicken and the longest (39896445 bp) in duck. Using the comparative sequence analysis, it was observed that the activin gene of chickens, turkeys and guinea fowl shared percent identity ranging from 91% to 95%. The percent identity reflects the degree of relatedness of species. Although closely related (90%) in ancestral line, the activin gene of guinea fowl and quail cannot be compared with guinea fowl-turkey (95%) nor guinea fowl-chicken (90%), in both biological functions and evolutionary relationship. Finally, the percent identity and similarity in function of the activin gene of guinea fowl, turkey, and chicken were in the range of 93% - 100%, indicating that the activin gene of avians possesses similar functions, well conserved and is very effective in performing functions like increasing FSH bindings, FSH-induced aromatization, improves wound healing and enhances scar formation, regulates morphogenesis of branching organs, and enhances ovarian folliculogenesis. The study, therefore, recommends farmers select and breed for activin genes in order to promote reproductive efficiency, thereby barricading species extinction.展开更多

However, despite provision of Comprehensive abortion care services with the liberal law, statistics at Kanyama First Level Hospital in relation to unsafe illegal abortions are alarming. This study sought to understand the Awareness on the TOP Act of the laws of Zambia among women of reproductive age 15 - 49 years at Kanyama First Level Hospital in Lusaka District. Purpose of the Study: To assess awareness on the TOP Act among women of reproductive age at Kanyama First Level Hospital in Lusaka, Zambia. Methodology: A convergent parallel mixed method design was conducted using both survey and in-depth interviews among women of reproductive age at Kanyama First Level Hospital in Lusaka District. The study surveyed 370 randomly sampled women aged 15 to 49 years old while the in-depth interviews included eight women purposively sampled from the survey population. Survey data was analyzed using descriptive and inferential statistics while qualitative data thematic analysis was used. Results: The study found that 37% of the participants were aware of the TOP Act while 63.8% viewed legalization of abortion for any reason as wrong. The study results also showed that widowed women were 8 times more likely to be aware of the TOP Act compared to single women (AOR: 8.262;95% CI: 1.105, 61.778). Women in business were significantly more likely to be aware of the TOP Act compared to those who reported having no occupation. (AOR: 2.61;95% CI: 1.246, 5.499). Limited access to information, the social stigma attached to abortion, health care providers’ attitudes, cultural norms, values and religious beliefs, restrictive legal requirements, and absence of a supportive network were some of the barriers affecting awareness and utilization of available safe abortion care services. Conclusions: The research findings concluded that a significant lack of awareness among women of reproductive age regarding the Termination of Pregnancy (TOP) Act. The majority of respondents held the view that abortion should only be legalized for medical reasons. Furthermore, there was a notable gap in knowledge concerning the penal code’s provisions on abortion.展开更多

Indeed, the interferon-ribavirin combination that has been used to treat hepatitis C has a virological response in only 45% of cases with significant side effects. The advent of direct-acting antivirals has changed the prognosis of cirrhotic patients with hepatitis C. DAAs have ensured a sustained viral response in the majority of patients. Our work aims to see the evolution of hepatitis C patients at the cirrhosis stage under DAA. We conducted a retrospective study over 15 years (January 2009, January 2024) including all patients with post-viral cirrhosis C, whom we divided into two groups: group A, cirrhotic patients who received ribavirin and interferon, and group B, patients on DAA. From January 2009 to January 2024, we conducted a study of 182 patients with viral hepatitis C, including 102 cirrhotic patients. The mean age was 55 years. 66% of patients were initially treated with the ribavirin interferon combination, while 34% received direct-acting antivirals (DAAs). Since the introduction of DAAs, the most commonly used regimens have been sofosbuvir/daclatasvir with or without ribavirin and sofosbuvir/ledipasvir with or without ribavirin. Group A achieved sustained virological response (SVR) in 60% of cases, with notable side effects. In Group B, SVR was 98.18%, with improved tolerability and fewer side effects than previous treatments. Fifteen patients developed hepatocellular carcinoma (HCC), with a significantly lower mortality rate in those treated with DAAs compared with pegylated dual therapy (p: 0.001).展开更多

Design: A descriptive exploratory study was conducted over three months among fourteen PPIUCD acceptors at a tertiary care health facility in Delhi, India. Face-to-face & telephonic in-depth interviews were conducted with a selected sample of PPIUCD acceptors who had later opted for its removal. Results: Participants (n = 14) aged 24 – 40 exhibited generally positive attitudes towards PPIUCDs indicating an indicate an understanding of the importance of PPIUCD in preventing unintended pregnancies. Menstrual disturbance and misplaced IUCD were major reasons for removal. despite their own experience necessitating the removal of IUCD, positive experience by other family members (mothers in law) in this study helped to keep the confidence on the contraceptive. Themes included (a) general experience of PPIUCD use (b) Health Facility accessed for removal of IUCD (c) Would she recommend it to others? (d) preferred contraceptive after removal of IUCD. Conclusion: Misplaced IUCD, missing thread, menstrual irregularities, and pain are all associated with PPIUCD and are important reasons for dissatisfaction. Appropriate, timely and supportive individualized care that address knowledge gaps, societal perceptions, and healthcare system challenges would certainly help in reducing dissatisfaction due to PPIUCD and thereby the removal rates.展开更多
